This package provides the following PostgreSQL modules:
- auto_explain
- pg_buffercache
- pg_stat_statements
- pgstattuple
The "auto_explain" module provides a means for logging execution
plans of slow statements automatically, without having to run
EXPLAIN(7) by hand. This is especially helpful for tracking down
un-optimized queries in large applications.
The "pg_buffercache" module provides a means for examining what's
happening in the shared buffer cache in real time.
The "pg_stat_statements" module provides a means for tracking
execution statistics of all SQL statements executed by a server.
The "pgstattuple" module provides various functions to obtain
tuple-level statistics.
